You are ordered to support the War of Resistance against Japan; China enters Level 1 combat readines

Navigator Zhao Dahe continued to stare at the observation telescope, looking at the ground.

He was looking for something.

The navigation chart indicates that after passing the Taihang Mountains and entering the North China Plain, there is a large river, a lake, and a mountain.

Those were the reference points he used to confirm his location.

There was no radio navigation, no ground guidance, only these landmarks measured from aeronautical charts, marked with pencil, and etched into my mind.

"The Yellow River has been spotted ahead." The observer's voice came through the earpiece from the back seat, carrying a hint of barely perceptible excitement.

Zhao Dahe glanced down.

A crack appeared in the clouds, revealing a winding, yellowish ribbon below, resembling a crumpled golden silk in the morning light.

Yellow River!

Zhao Dahe marked a point on the nautical chart, touched the paper with the tip of his pencil, paused for a second, and then lifted it up.

He glanced down at the spot, then looked up at the golden ribbon outside the window, and a slight smile appeared on his lips.

"The course is correct, there is no deviation."

His voice returned to calm, as if he were stating something perfectly natural.

"Maintain 92.5 and keep going!"

The formation continued flying eastward.

The North China Plain stretched out beneath the aircraft, with fields, roads, and villages lying there quietly, like a map shrunk countless times.

Gao Zilong glanced at the fuel gauge; the needle was steadily on the mark, everything was normal.

He glanced out the window again; the sun had risen a little higher, and the light was brighter, making the edges of the wings appear white.

"Attention all aircraft, check fuel levels," he issued the order.

"Number Two, fuel level normal!"

"Number three, normal!"

……

Gao Zilong nodded.

Fuel consumption is within expectations, and the wind direction is more favorable than anticipated. At this speed, the fuel supply is more than enough for the return trip.

He took a deep breath and slowly exhaled, and the tension in his chest eased a little.

Zhao Dahe started calculating again.

He calculates the position every fifteen minutes, using speed, time, wind direction, and heading to deduce where the plane should be now, and then confirms it with landmarks.

If the calculation is correct, continue flying; if it's wrong, adjust the course to make up for the deviation.

There were no satellites, no radar, no ground guidance, only a chart, a slide rule, a pair of eyes, and a brain.

"Altitude 8,000, speed 980, wind speed 11, correction angle..."

His pencil flew across the paper, marking names, calculating once, checking once, calculating again, and only when all three calculations were the same did he dare to mark them on the aeronautical chart.

"Theoretically, it should be located 80 kilometers east of Jinan, and Mount Tai should be visible in front of it."

He looked up and squinted at the window.

The clouds were still so thick, a vast expanse of white, obscuring the ground.

His fingers tapped twice on the chart, not in a hurry, but with a heavy tap.

Mount Tai is one of the most important landmarks on this route; beyond Mount Tai lies the sea.

If he can't see Mount Tai, he can't confirm its location, and if he can't confirm its location, all subsequent calculations may be off-target.

"Lower altitude and break through the clouds," Gao Zilong's voice came from ahead.

Before Zhao Dahe could speak, Gao Zilong had already gently pushed down the control lever.

The nose of the aircraft dipped slightly, and the pointer on the altimeter began to slowly rotate.

Eight thousand, seven thousand eight, seven thousand five, seven thousand two...

The clouds drew closer and thicker, and the white fog shone on the windshield, obscuring everything.

Zhao Dahe gripped the pencil tightly in his hand, his knuckles turning white.

7,000 meters.

The clouds suddenly parted.

It didn't disperse slowly; it was as if someone had ripped it open. In an instant, the entire white sea of ​​clouds was torn open, revealing the gray-green earth below.

Zhao Dahe's eyes widened suddenly.

Mount Tai!

He saw Mount Tai!

Nantianmen and Yuhuangding, those coordinates he had marked countless times on the navigation chart, were now embedded in that mountain, gleaming with a bluish-gray light in the morning glow.

"Mount Tai! I see Mount Tai!" Zhao Dahe's voice exploded from the earpiece.

"Right to the left front, heading 92.5, not off course! Not off course at all!"

Gao Zilong glanced down, a slight smirk playing on his lips, before quickly closing his mouth again.

His hand rested on the joystick, and his fingers flicked lightly twice, as if he were playing a silent melody.

"Maintain course, stay on course."

Gao Zilong's voice was still as steady as ever, but there was a slight tremor in the last syllable that he himself did not notice.

Zhao Dahe marked a point on the nautical chart, with the tip of his pencil pointing to the location of Mount Tai, and paused for a while.

His hands were trembling slightly.

Finally, he wrote a line of small print next to that spot—

"Eight one one nine two, time... Cave turn cave eight, cross Mount Tai!"

The formation flew over Mount Tai.

The sun shines from the east, casting long shadows of the mountains across the plains below, like an arrow pointing towards the sea.

Gao Zilong glanced at the shadow, then at the heading indicator, which remained firmly stationary at 92.5.

"Attention all aircraft, we are about to enter the Yellow Sea!"

"Altitude 7,000, speed 980, heading 92.5, estimated time to cross the coastline 8 holes 3 holes."

Zhao Dahe lowered his head, his eyes fixed on the navigation chart.

His hands moved back and forth on the slide rule, his pencil scribbled names on the paper, and he muttered to himself.

He calculates the position every fifteen minutes, using speed, time, wind direction, and heading to deduce where the plane should be now, and then waits for the next reference point to confirm.

After passing Mount Tai, there were fewer and fewer reference points. There was nothing on the sea except water and sky. He could only rely on calculations to navigate between the sky and the water.

"Wind speed is 9 meters per second, wind direction is northwest, yaw angle correction is 0.3 degrees, actual heading is 92.2."

He recited a set of data in a very low voice, as if he were talking to himself or confirming with Gao Zilong.

Gao Zilong didn't speak, but gently pushed the control stick with his left hand. The nose of the plane tilted slightly by less than half a degree, and the heading pointer on the instrument panel slid from 92.5 to 92.2 and stabilized.

"The island ahead should be Jeju Island."

Zhao Dahe tapped his finger on the aeronautical chart. He had marked that little black dot countless times; he could find it even with his eyes closed.

"Based on the speed, it should be about 50 kilometers to the left and front. If the visibility is good, we should be able to see it."

Gao Zilong narrowed his eyes, then narrowed them again.

He saw it.

Jeju Island, confirmed.

Zhao Dahe marked a point on the nautical chart, with the tip of his pencil pointing to the location of Jeju Island, and paused for several seconds.

"81192, time... Cave 837, past Jeju Island!"

The formation continued flying eastward.

The sun rose higher and higher, and the light grew brighter, illuminating every corner of the cabin clearly.

Zhao Dahe started calculating again, speed, time, wind direction, course, over and over again, each time matching perfectly, each time fitting together flawlessly.

"We are entering the Tsushima Strait ahead."

"Cornering course correct, speed normal, estimated arrival time at the Japanese headquarters coastline..."

"Dong Jiu Yi Ba!"

(I wonder if anyone noticed these numbers. Tomorrow is May Day, let's have some fun with the Japanese devils!!)

(Please give me a tip!!!)
